论文摘要
伽马工厂的倡议提议通过在SPS和LHC存储环中生产，加速和存储高度相对论，部分剥离的离子光束来开发CERN的新型研究工具。通过激发用激光器储存的离子的电子自由度，将通过正确地将高能窄带光子束通过正确地沿离子传播方向达到峰值的二次辐射来产生。它们的强度每秒最高$ 10^{17} $光子，将比当前在特别有趣的$γ$中运行的光源的数量级高几个数量级 - Ray Energy域达到400 MeV。本文回顾了可以通过利用主要横梁进行存储环中循环的部分剥离离子的光谱以及通过使用二级高能光子束提供的原子物理学机会来提供的机会。伽马工厂将通过光谱和测试自然基本对称性的新颖方式实现突破性实验。
The Gamma Factory initiative proposes to develop novel research tools at CERN by producing, accelerating and storing highly relativistic, partially stripped ion beams in the SPS and LHC storage rings. By exciting the electronic degrees of freedom of the stored ions with lasers, high-energy narrow-band photon beams will be produced by properly collimating the secondary radiation that is peaked in the direction of ions' propagation. Their intensities, up to $10^{17}$ photons per second, will be several orders of magnitude higher than those of the presently operating light sources in the particularly interesting $γ$--ray energy domain reaching up to 400 MeV. This article reviews opportunities that may be afforded by utilizing the primary beams for spectroscopy of partially stripped ions circulating in the storage ring, as well as the atomic-physics opportunities afforded by the use of the secondary high-energy photon beams. The Gamma Factory will enable ground breaking experiments in spectroscopy and novel ways of testing fundamental symmetries of nature.
